It supports up to six expansion modules, allowing users to scale I/O capacity as system requirements grow. The controller integrates a Mini-DIN serial port that supports DF1, DH-485, ASCII, and Modbus communication, enabling easy connection to HMIs, SCADA systems, and external devices. Its durable construction, wide operating temperature range, and long mechanical relay life make it well suited for demanding installations. Key Features: Mixed I/O Architecture: Provides 20 standard DC inputs, 4 fast DC inputs, 8 relay outputs, 7 DC FET outputs, and 1 high-speed FET output for flexible control. Expandable Design: Supports up to six 1762 expansion modules to increase system capacity. Versatile Communications: Includes an 8-pin Mini-DIN serial port for DF1, DH-485, ASCII, and Modbus protocols. High Relay Durability: Rated for 20 million mechanical cycles with AC and DC switching capability. Robust Electrical Ratings: Handles 24–125 VDC and 120–240 VAC relay loads with defined current and isolation specifications. Industrial Environmental Tolerance: Operates from 0 to 55 °C and withstands 30 G shock and 5 G vibration. Integrated Trim Pots: Two onboard potentiometers enable local adjustments to internal registers for testing or simulation. Compact Mounting Options: Supports panel or DIN-rail installation for flexible deployment in control cabinets. The 1762-L40BXBR delivers the reliability and precision required for stable machine sequencing and discrete automation control.
